The Portuguese had already lost Hormûz
(now in Iran) in the Persian Gulf in 1620, then in `Umân the fort of uâr in 1643 and the town of Muscat in 1650.
The revived `Umân kingdom developed a navy and in 1652 landed on Zanzibar and destroyed the Portuguese town.
As for the Church on the north coast at this time, a report by the Dominican priest Vittorio Ricci in 1654 says that Mogadishu was in Muslim hands and the Augustinians had left it.
Augustinians were still in Mombasa, while on Zanzibar and the islands to the south there were Christians under the care of Augustinians and Dominicans.
In 1657 in Ampaza (Faza on Pate island) an Augustinian was sending young converted slaves to Goa so that they could grow up without danger to their faith.
In 1661 the `Umân forces again attacked Mombasa, but left because they could not take Fort Jesus.
By now the Dutch (i.e., from Holland) had weakened Portuguese naval power along the coast and on the Indian Ocean, and along the coast a number of cities were opposing the Portuguese.
These Africans invited a naval force from the Arabian principality of Oman to the area to drive the Portuguese away.
The navy of Oman came in 1652, 1660, 1667 and 1679, and they attacked the Portuguese repeatedly.
In the 1690s another naval expedition from Oman arrived at Mombasa, and in 1698, after an attack lasting thirty three months, a naval expedition overran Fort Jesus.
They killed about 1,000 Portuguese and some 5,000 of their Swahili allies.
As a result of the capture of Fort Jesus, the Portuguese lost the whole northern coast of East Africa, and were left only with Mozambique island and stations to the south.
Portuguese military forces made one more effort in 1728; they captured Mombasa but lost it again in the following year.
Portugal lost forever its hold on Mombasa and the coast north of Cape Delgado, and Arab power along this coast was accepted as supreme.
The Augustinian presence in the northern coast of East Africa abruptly ended.
The last prior of the Augustinian priory of Mombasa was Antonio of the Nascimento O.S.A.. He was appointed on 2nd December 1729.
In January 2006 Archbishop Boniface Lele of Mombasa expressed a hope that the Augustinians might take up an apostolate in Mombasa. He is aware that they served there previously for 130 years and had a number of martyrs there in 1631.
